Free to check. Paid to never think about it again.
Every plan verifies against all 78 trust stores. You're paying for volume, monitoring and automation — not for the check itself. Anonymous visitors can run 5 checks a day, no account needed.

Why is the check itself free?
Because a one-off check is how you discover the problem. What costs us money — and saves you incidents — is watching your domains every day and telling you the moment something changes.
What counts as a "check"?
One domain (or pasted certificate) verified against the trust stores you selected. Selecting all 78 stores is still one check.
Can I cancel anytime?
Yes. Monthly plans cancel at the end of the cycle. Your account downgrades gracefully to Free — nothing is deleted.
Do you store my certificates?
We store fingerprints and metadata for signed-in users' history. Anonymous checks are ephemeral — nothing is kept.
